Con

Somewhat expensive

Con

The version with full features is not opensource. Parts of the code are under apache licence though.

Con

Bugs are not solved as often as they should

They are more interested in adding new features or issuing new versions than solving bugs.

Con

Slow startup

Con

Uses too much RAM

Con

Lack of plugins

IntelliJ supports a very small amount of plugins. Althrough thesse are 'quality approved', many features are missing and can't be implemented because of that.

Con

Cannot open multiple projects in the same window

Con

Standard hotkeys behave differently

Seems like hotkeys assignment in Idea has no logical consistency.

Like «F3» is usually next match, «Ctrl+W» - close tab, etc — they map to some different action by default.There is a good effort in making the IDE friendly for immigrants from other products: there are options to use hotkeys from Eclipse, and even emacs. But these mappings are very incomplete. And help pages do not take this remapping into account, rather mentioning the standard hotkeys.

So, people coming from other IDEs/editors are doomed to using mouse and context menus (which are rather big and complex).
